Which dehumidifier should you use for a garage?

Did you know that high humidity levels in a garage can destroy your tools, electronics, and documents?

Humidity creates a perfect environment for corrosion to occur. As a result, metals and electronics tend to rust and lose their resistance and conductivity factors. If your electronics rust, they will not only malfunction but can also short circuit –which can end up causing accidents. To avoid this, you need the best dehumidifier for your garage.

it is essential to control humidity levels in your garage regardless of the season. While many homeowners prefer heating up the garage during winter, this is not only expensive but also leaves your garage vulnerable to humidity during other seasons.

A dehumidifier will help you to maintain the right levels of humidity, which is about 40-60%, in the garage. To achieve this, you need to get a good dehumidifier.

What size dehumidifier do you need for a garage?

The right size of a dehumidifier for your garage will depend on the dampness and length of the room.

Start by measuring the length and width of the space you want to dehumidify and multiply the values you get in square meters. Next, determine how damp your area is by looking at any signs of humidity.

Note that a garage can be Extremely Wet, Wet, Very Damp, or Moderately Damp (read more about this later in the article). If the room is:

  • Moderately Damp and measures 500 square feet and below: you need a dehumidifier that has a capacity of between 10 and 20 pints.
  • Very Damp and measures 500 square feet and below: choose a unit whose capacity is between 12 and 32 pints.
  • Wet and measures 500 square feet and below: buy one with a capacity of between 14 and 38 pints.
  • Extremely Wet and measures 500 square feet and below: go for a device with a capacity of between 16 and 44 pints.

In essence, you should buy a dehumidifier whose capacity is higher than the size of your garage.

Should I get a heater or dehumidifier for a garage?

You can control condensation in your garage by using a heater or a dehumidifier. A heater will keep the temperatures stable and reduce condensation.

But a dehumidifier is much more useful, in this case. This is because it will control moisture levels in your garage by removing excess water from indoor air. The unit will then reheat the air and exhaust it back into the room.

Furthermore, dehumidifiers have a humidistat. It is a feature that allows you to set the right level of relative humidity in the surrounding based on the dampness of the area.

Factors to consider before purchasing a dehumidifier for your garage

When ordering your dehumidifier, you have to pay attention to a couple of things. Without keeping these factors in mind, you might end up with an ineffective device. These factors include:


Size is crucial when it comes to buying a dehumidifier. Ideally, choose a unit based on the amount of water it can extract from the air within 24 hours.

Examples of sizes in pints are 30, 50, 70, etc. A rule of thumb is to purchase a device that covers larger square footage of your garage.

Moisture levels

Consider purchasing a dehumidifier that will extract the amount of moisture in your garage. You can classify the moisture in your room as extremely wet, wet, very damp, and moderately damp.

Most homes fall under moderately damp conditions. The only exceptions are in cases where the garage has mold, leaks, musty odor, and other issues.

Desiccant or refrigerant dehumidifier

Dehumidifiers can either be desiccant or refrigerant. In our garage dehumidifier reviews, we recommend desiccant units for areas that experience temperatures below 18 degrees. Refrigerant models are applicable for hot and humid zones.

Features to consider before buying a dehumidifier for your garage?

The best dehumidifiers for a garage should have these features:

  • Energy efficiency: Power usage varies between dehumidifiers. But energy efficiency will also depend on the size of the unit. Consider going for a device that gives the highest amount of energy performance.
  • Auto-Restart function: An auto-restart function offers an extra level of convenience to the device. It comes in handy in regulating humidity automatically. It is also helpful in powering up whenever there is a power outage.
  • Timer controls: Ideally, you should choose a unit that has a timer because it prevents you from setting it up manually. Besides, a timer allows the device to work in a specified setting 24/7.
  • Drainage: Consider buying a unit that drains the water collected continually. It will prevent you from emptying it periodically.

Other features you should pay attention to are washable air filters, user-friendly controls, and integrated humidistat.

Does a dehumidifier work in a cold garage?

A dehumidifier will work in any garage that suffers from standing water and condensation. Condensation causes consistent moisture that can result in mold and odors. It can also cause damage to the structural integrity of your house if left unattended.

By placing the unit in your garage, it will prevent these issues and ensure minimal maintenance over time. The device will control moisture levels and reduce the humidity levels needed by mold spores to grow. Besides, it is also helpful in preventing wood rot and damage to your tools.


The best dehumidifiers for a garage are those with a capacity that is higher than the size of your room. It should be energy-efficient, ultra-quiet, and useful in lowering the humidity in any space.  Additionally, you should also consider a unit that comes with a removable and washable air filter for easy maintenance.
